Problems solved by technology

[0006] However, in the vehicle body manufacturing form in which the floor assembly centered on the floor panel is placed on the front body assembly including the connecting member and spot welded, the instrument panel lower member and the underbody that separate the vehicle compartment and the engine compartment The joining part of the panel is located in the back side of the connecting member, and the connecting member will hinder the spot welding, so it is necessary to provide a hole for inserting the welding gun in the connecting member
[0007] Therefore, a cover for closing the hole is required, and there is a problem that the number of parts increases, and there is a problem that a precise jig is required in order to accurately align and combine the positions of the holes.
In addition, there is a problem that the transferability of the impact load at the portion where the hole is provided decreases

Abstract

Disclosed is a vehicle body panel joining structure which is provided with: a structural frame (30b) having a ridge line in the lengthwise direction, which has one section joined to a first vehicle body panel (44) and another section joined to a second vehicle body panel (43); an overlap part (61) which overlaps the first and second vehicle body panels and is disposed in such a way that the structural frame straddles the overlap part; a depressed part (64) which is provided at a position avoiding the ridge line on the structural frame and is abutted by the overlap part; and a spot-welded part (65) which is joined to the depressed part, the first vehicle body panel and the second vehicle body panel at the overlap part by means of spot welding.

Description

technical field [0001] The present invention relates to body panel joining configurations. [0002] this application claims priority based on Japanese Patent Application No. 2009-285133 for which it applied in Japan on December 16, 2009, and uses the content here. Background technique [0003] There is known a vehicle body structure provided with connecting members for the rear ends of a front side frame arranged on both sides of an engine compartment in the front-rear direction, and the lower ends of the front-side frames arranged in the front-rear direction on both sides of the vehicle compartment. A front end of a side sill is connected to a front end of a center frame disposed at the center of the cabin in the vehicle width direction in the front-rear direction. [0004] Because the connecting member has: an outrigger extending toward the outside in the vehicle width direction and obliquely rearward and connected to the front end of the side sill; The center frame prot...
